This invention relates to improvements in apparatus for attaching shoe heels of-the kind used for sport shoes wherein the tread face is provided with projecting spikes.

5 T-fe'el nailing machines supplied lay-menu facturers of shoe machinery are-so designed that the heel attaching. nails can be driven accurately only if the heel has a smooth tread, that is, atop lift without spike or it other non-slip projections. It is essential, in the heel attaching operation, that the heel to benai'led is clamped securelybetween the die block and'the-jack of thei'iailingmachine,

The die blocks of nailing machines offered it tdthe made,- such as the lightning mil s? enerally in use, have a flush under face or engagingi the treadfa ce ofthe heh If a sport shoe heel is to be attached the spikes engage the under face of the die block and hold the heel away from the die block which 1 is fatal to an accurate driving of the heel attaching nails; This condition has resulted "in many cripples due to bent heel nails and manufacturers of sport shoes provided with spiked heels have had to resort to the slower and more expensive attachment of the heels by hand nailing.

Theobject of the present invention is to improve the construction of. apparatus for 3o attaching heels. and more particularly to im-' prove the die block of heel nailing machines,

in a manner to insure proper attachment of spiked heels to the shoe when machine nailed.

To the accomplishment of this ob]ect, the

invention comprises aheel nailing machine having the features and combinations of parts hereinafter described and then particularly pointed out in the appended clalms.

The features and scope of the invention 140 will best be understood'from a-descr1pt1on of the preferred embodiment thereof illustrated in the accompanyingdrawings, in which: 7 1

Figure 1 is a view, in front elevation, of a 4'5 portion of a representative type of heel nailing machine showing the relatlo'nof the nailing head, die block, sport shoe and jack after the heel nails have been driven, the shoe and the central portion of the die block both being shown in section; Fig. 2 is an under face ,a gang of twelve nail drivers for drivp 4' 'shows,-in perspectiveguone';type of "SPlkGCli heel that may successfully :beS nailed by following the teaching. of the presentinveution andJFig. 5 shows,- in perspective, the sport shoe heel of, 4; attached to a sioek 'l. Y J 1' In the embodiment of the'ginve'ntion illustrated in the drawing, it being fullyunderstood th-at-theusefulness of: the invention is not limited to attaching; thegparticular sport shoe heel shown which is the subject-matter of a to-pending apl'ication for patent Serial NoL 380,020'filed January 3, 1929, a sufficient portion, of shoe nailing machine is shown in Fig; Lto enablethe application oft-heinentionthereto to;hemndersto'od,namely the nailing. head l0,;thed;iebloo1i;l,2s andthe jack l havingia shoe 16 ther,eon.; ;The-shoe,after 1 having ,been bottomed is pl;aced; on thej j acik as usual-, and the-spiked heelhavijngbeen positiened under-the improvedudie' block-the. fi-B;Il-1-Hg;;m&GhlDG passes; through its usual ecycle ofg operations and the spiked heel is firmly and-correctly attached.

In order to accomplishthis,provision is madeg for seating: thetreadi face ofthe sport shoe heel, regardless-of its projecting spikes, flushagainst; the perforated central position of the die block through which the drivers" ;18goperate. As shown best by Fig. 5 there are, in thefpresent instance,

,ing an equal number- "of heell attaching nails 2O throug h] twelve parallel die block nall passages 22 so gro' iped afsto setlthe nailssin thejv margin of the heel; To be serviceable the spikes mustz be located near 'the e dgeof the heel. Therefore the top lift ;of the ;illustrative sport shoe Y heel Elias. .siX spike s24: set in its. margin, the-heel attaching :nails 20 beingfidrivenin 't-himargia also but vbetween thej spikes This: arrangement of nails'and-spikes highly importantas will presently be understood, V

Referringifto 3 itfwill be seen thatlthe .nai-lpassa es2'2' athr ougzl the die block form figure o flieel lift shapebut leavingsolid portions 26 of the metal die bloc-k between each pair of passages. Obviously if a spiked heel, for exampleas illustrated in Fig. 4, is held under a die block having merely the usual nail passages the spikes will engage the solid portions 26 and} the heel will be held spaced from the plane of emergence of the gang of .nail drivers l8 by.1a.'distanc,e

erally fatal to its accurate attachment, to the shoe.

s In order to overcome the fcondition just de; scribed each solid die block portion 26 to be engaged by .a spike 24 is recessed as at 28 (Figs. 1 and 3), in. a definite position rela-.' tive to the adjoining nail passages 22. The

rccessesare proportioned to receive the heel spikes which, without undue pressure, may

bepushed home, i. e., until the heel stock is incomplete engagement with the die block.

.blook and-its spikes 24Y-are inserted in the similar spacedrecesses 28 it is not only so 10- cated as to insure accurate nail driving but the drivennailsare definitely'spaced between the spikes-as fine shoemaking requires.

c It will be understood fromjtheforegoing description that theusefulness of the 'inven tion is not limited to any particular heel at- V taching machine, nor to attaching a spiked a heel to any particular kind of shoe. Furthermore, in the descriptionand claims the deequal to the height of the spikes 24.
